Los Angeles Unveils New Groundwater Treatment Facilities to Boost Drinking Water Supply
Los Angeles Mayor Bass and city leaders inaugurated new groundwater treatment facilities, a climate action initiative by LADWP, designed to purify up to 43 million gallons of contaminated groundwater daily for safe drinking water.

Los Angeles, CA, August 25, 2026 —
Los Angeles, CA – City leaders, including Mayor Karen Bass, have officially inaugurated new groundwater treatment facilities aimed at enhancing the city’s drinking water supply. The initiative, spearheaded by the Los Angeles Department of Water and Power (LADWP), represents a significant step in the city’s climate action efforts.
The newly operational facilities are designed to treat contaminated groundwater, making it safe for consumption. According to LADWP, the system has the capacity to purify up to 43 million gallons of groundwater each day. This increased capacity is expected to bolster the reliability and safety of the local water supply for residents.
The project is part of LADWP’s broader strategy to increase the use of local water resources and reduce reliance on imported water. Investing in advanced treatment technologies for local groundwater sources is a key component of the utility’s long-term water resilience plan, particularly in the face of changing climate conditions and potential water scarcity.
Officials highlighted the environmental benefits of the project, noting that purifying and utilizing local groundwater reduces the energy consumption and carbon footprint associated with transporting water from distant sources. The initiative aligns with broader climate action goals set forth by the city and LADWP to promote sustainability and environmental stewardship.
Further details regarding the specific technologies employed at the treatment facilities or the timeline for full operational capacity were not immediately provided. The inauguration marks a milestone in LADWP’s commitment to providing a safe, reliable, and sustainable water supply for the city of Los Angeles.
